Normal flora are those microorganisms that resides in a living organism without causing it harm or diseases.
These normal flora become established in different parts of the body from birth such that the normal flora found in the mouth is not the same as the one found in the colon of the alimentary tract.
From research works, the large intestine (colon) is known to contain 100 billion per milliliter of fluid culture.
The massive numbers of bacteria in the large intestine (colon) creates a great special variation in the flora. The streptococci and lactobacilli found in the colon often adhere to cells by means of capsules surrounding the bacteria.
